"no LL WHoM 1T MAY gooNe'EnN:

Be itk'nowtb-at' I, Inorn WIEAND, of the city of Philadelphia, and Stnte` Pennsylvania, hqve invented certain., useful V-I mpi-o"tamente in theonstrncton of Steam-Generatore, and `the furnnces for heating' the Home; land I delhetehyeolarevthnt the ollowig is n fnll, clear, rind exact description thereof, reference honghad to the :17.cceonxprsnying drawings, and the lettorsrof reference marked thereon.

- Figure 1 bows'n frontrelvntion, pnr'tly itiv section. Figure 2 shows n side elevation, partly in section. 4 l Eignre 3V 'shows' en enlerged section of one of the tbes andi-the adjacent ports.

The 'nntue of my intention relates to a system of constructing and modifying the steam-generator, for

which Letters lntent of the United States, No. 67,621 were granted to myself, 'by which means I om enabled to nuke a, stento-generator conveniently portable for shipment, and more o tl'eotunlly to burn the fuel, and utilize lthe heat so produced, ,u nd the improvement of' some of the Ininor detel's'for promoting tho safety-und convenience of use ofthe oppurotue. n Y. v. i

This eteamLgenerntor consista of n euries of tubes YB, placed. iu\rows, in connection `with strongetenm-tigh't veaeeleG, by @rowing-.them on, or by any other knonrn' mea'ns of hnkng n steam and water-tight joint, ond closed otith lower-ends by'mjenns of ftheeops M. A V

The vfu'mztien of" the valves T nro to admit. the water `to the' severnlseeti'onerfl, and Jef the valves S, to pormittho etemh'to 'poss to theinnin'qtenmpipe F, and in the event of the ruptnreo-nny of tho tuheef er' 'cupe M, to prevent'tbeontentefnf any ofthe other sections thon the one immedatelyconneeted 'with tho brolxvonfpurt being liac'hnrgedt'brongli the vent thus" made.

'Fi'g'nrcA shows nn enlarged viewlof the hond-hole plate O, which is cnet Awith n ppekef, to ieeet'othe 4bend of; the; holt I?, bymenne of which ie drawn by the `rrmt It and yoke or vbridge Q, to its bearing, .n.'ndposjsesses this axlvnntag'e ovens-uch plates as heretofore meile fol-'same pnl-Apnea, that reason of the boltheacl tting easily. in ny socket, instead `of being rigidly fnstenod to the plete, suoient motion takes place between tho 'hendpfthe bolt P andthe p'lateO, to permit .the rim ofthe plate 0 to picas eqnally egeinstali parte ofits sent. i The nrrangemont of the furnhoe is another point of peou'lnrndvnntn'ge in tbisinv'ention. yThe oblique front wall U-lenvos between itself and the greteslv, and the front row of tubes B, a space in 4which gases are 'forneattronl the fuel, and'is innnehl position as to'rndinte :nd reflect hea't'upon `the tlubeB of the generator, und the gases which poss intothocouibustiongchamber below the-tubes, nod bythia menus nth'orough combuetion `of gases among all the tubes is'eieetually secured,

The front wall U may sometimes' be ndvnntngeouely mudo in n curved form,`o.e ehowby the dotted linea in the drnwingpahdpljovided with adoox', W; 'to feed in fuel when burning shevinge or saw-dust, 81,0.

The combination of fnel placed upon the gratos V, andthe lxpply` of gnees `to Ithe oombneti-on-clmmbcr over th'e grote, and also below-and enong. the' tubes, nire controlleil and regulatedrbyv the regstar'X admitting eirto the ash-pinwhlchin other respects is nir-tight ir' is admitted above the-fuel in regnlatabl quantities, and heated nnddietrihnted by passing through Extending the whole length 'et' the sc rcen, inside of vits wire covering, they answer the purpose of beaters, the grain falling from one to the'other of themLus the screen revolves, and the dirt, dto., being thus thoroughly separated from it.

` They, also', spreading from eeoh other, serve as conveyors to curry the grain along towards the lai-ge end of the sereen.A Y

' The sieve s may very in 'neness from one end to the other, if desired, so as to separate the diii'erent species of impurities st different points.

The machine has been very thoroughly tested, and yfound to work in every respect in thclmoet satisfactory manner.

Having thus described my invention, what I olnm se new, and desire to secure by Letters Patent, is- 1. The arrangement of the sieve I, with the hopper C, conveyor D, and sei-een B, substantially as described. 2. The arrangement of the hopper G, sieve I, serew-eonveyer D, screen B, inclino J, and spente E and F, substantially ns described.

To the above specication of my improvement Ihsve signed my hund,thisl24th day of February, 186 8.
